In a now-deleted tweet, Canadian musician Grimes (aka Claire Boucher) defended her tech billionaire boyfriend, Elon Musk, against claims that he has stopped his Tesla employees from unionizing.

"he has never prevented them from unionizing," wrote Boucher. "it's quite literally fake news. trust me, i've investigated this heavily and even visited factories etc."

Musk's Tesla has faced multiple allegations that it has moved to stop union drives at its factories. In April 2017, the United Automobile Workers union filed four charges with America's National Labor Relations Board, alleging Tesla was illegally surveilling and had attempted to coerce workers who were distributing information about a union drive.

Musk has previously denied the claims on Twitter, saying there was "nothing stopping" his employees from voting to be in a union.

@dmatkins137 @ShayneRarma @NASA Nothing stopping Tesla team at our car plant from voting union. Could do so tmrw if they wanted. But why pay union dues &amp; give up stock options for nothing? Our safety record is 2X better than when plant was UAW &amp; everybody already gets healthcare.

The union tweet was just one of many that Boucher has now deleted, saying the conversation was "way too nuanced" to have over Twitter, and that she would rather debate "in an organized way."

@cocteau_twinks @jcfrancisco @thefader hm.. deleting my tweets abt this shit bc this is way too nuanced of a convo to have over twitter. again, down to hash out in ama later, down to hear opinions. in any case love and respect to all. plz try to see me as a human being an not just an extension of another person 🖤

Other tweets from the artist defending her relationship with Musk are still up; however, she did make the point that who she's dating "is irrelevant to my music."

@cocteau_twinks @jcfrancisco @thefader that said i respect yalls commitment to social justice. we all gotta work to make the world better,, i’ll stay on my game too.don’t wanna answer more questions cuz who i’m dating is irrelevant to my music lol, speaking of gotta get back 2 work 🖤🖤🖤😥

bro grimes is like a 35 year old white woman who is a millionaire. there's a way bigger chance she's going to start tweeting in Sperrys and Madwell in a month versus changing elon musk's mind on unions
